Case 1: 5 is in the exponent of x.
x^5 = 12, then x = fifth root of 12 = 1.64375182952
Case 2: 5 is the coefficient of x.
5x = 12
x = 12/5 = 2.4

Does x5 mean 5x, or x^5?
If 5x = 12, then x = 2.4.
If x^5 = 12, then x = 1.643751829517225762308497936231

x5=12
-- -- ( u / both sides by 5 in order to find x)
5 5
x= 2.4
checking
x5=12 ( for x u got 2.4 )
2.4*5=12
it works out great, so ur answer for x is 2.4.

well thats an easy one..
x5/5 = 12/5
x = 2.4

x5=12
x5/(divided by)5=12/5 (divided by 5)
x=2.4
verified is 2.4 x 5=12

Marcella, do yourself a favor and do your own homework. You've asked for help with 11 math questions in the last couple of hours, and they are all variations on the same concept. This shows that you are not even trying - don't continue to cheat yourself or you will just end up failing.
See your teacher for some one on one help if you don't understand, it's better than copying solutions from others.

if u mean X*5 = 12
X = 12/5
X = 2.4
but if u mean
X^5 = 12
X = 12 ^ 1/5
X = 1.6438

5x = 12
therefore x = 12/5
therefore x = 2.4
